Application led September l2, 1921.

To all fio/0m t may concern Be it known that I, ,latins CLARENCE BURNE, a citizen of the United States, residing` at Test Chelmsford, in the county of Middlesex and State of h/Iassachusetts, have invented new and useful Improvements in Transmission Band Materials, of which the following is a specification.

This invention relates to transmission bands such as are used for gripping and holding` the various drums of a planetary transmission such as is used on a Ford automobile7 and has for its object the provision ot a novel band lining which will not glaze and consequently becomer useless when run in oil. Ordinarily suoli band lining is made ot woven fabric, asbestos tiber, other librous materials having cork inserts, and various other substances. It has, however, been ascertained from long experience that band linings of such material shortly become useless. Gwing to the fact that the oil in which the drums rotate burns into the cotton bands they become hard and glazed so that they lose their gripping' action, the cork inserts break up and the pieces interfere with the magneto action. It is with these objections in view that the present invention has been designed.

More specifically, the object ot the invention is the provision ot a band lining which is constructed entirely or partly ot animal material, such as camels hair or the like which, being` naturally oily, is in its element when saturated with the oil used in the transmission otl an automobile.

With the above and other objects and advantages in view, the invention consists in the details ot construction to be hereinafter more 'fully described 'and claimed and illustrated in the accompanying drawings in which,

Figure l is a side elevation or" a band having a lining constructed in accordance with my invention, i

Figure 2 is a plan view of the lining alone,

Figure 8 is a cross-sectional view therethrough in the line 3 3 of Figure 2 and Serial No. 498,973.

Figure 4f is a longitudinal section on the line 4 4 of Figure 2.

Referring more particularly to the drawings the letter A designates a contractile band of the ordinary type which is provided on its inner periphery with a suitable lining. In carrying` out the present invention I provide a lining which is designated by the numeral lO and which is woven from a suitable filler thread such as cotton, or the like and animal hair, preferably camels hair. The transverse strands of the tiller thread are indicated by the numeral 1l and the longitudinal strands of camels hair are indicated by the numeral l2. The camels hair is woven in and -out of the filler threads in a well known or conventional manner and may extend entirely to the edges of the bands or may extend only to the dot and dash lines on Figure 2 ot the drawings with a selvage 13 ot cotton or other material it preferred.

In the use of a band lining of this material it will be seen that there will be no hardening or glazing for the reason that camels hair is naturally oily and is theretore in its proper element and in a natural state when saturated with oil.

While I have shown and described the preferred embodiment of my invention it is ot' course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention I claim:

A transmission band lining consisting` of a base formed ot transverse strands of fiber filler threads and longitudinal strands of animal hair, the side edges of the band having the outermost longitudinal strands formed of fiber thread to define a selvage of base material.

In testimony whereof I aiiix my signature.
